I played 3&K a lot as a kid but I never actually owned it myself until fairly recently. I gotta say, I enjoy this game a lot more now that I am no longer a dumbass child and I actually understand the devs' design intentions. I don't think I have to be the thousandth person on this site to explain what makes classic Sonic so great, just know I really like this one.

By the way if you want a legal way to play this, it's on Steam for like $5 right now and it's going to be delisted on May 20th (2022). Thanks Sega, very cool.
